Feature suggestion: to have a "random lesson" button
Before the update, I used to use the "practice" button to refill the "strength" of my skills. It was useful for me to practice German in all skills at the same time. I used the "strength" bar to check my progress, and when everything was "gold" I just started to learn new skills
Now that we have crowns, the "practice" button leads to nothing => It's random and you have no visual thing to show you if you recently learnt a specific skill or not.
One interesting thing would be to have a similar button but instead of "practice" it would be "learn a random skill" and it would push you into one of the lessons you didn't do yet. This way, if you don't want to focus on a particular skill, you can just do it randomly
There is one if you don't mind using a script. Have a look at the thread: "Not sure what to study next after crowns? Let's fix that"
The script I found in the above comment is exactly matching my needs. Well done ! Duolingo should take a look on this awesome feature
According to Duolingo the practice button isn't random, but takes into account what your worst words are. It doesn't give you any Duolingo-progress, but does help your understanding.
